SYCO: Symposium Mechanically Controlled Electrical Conductivity of Oxides

SYCO 1: Mechanically controlled electrical conductivity of oxides

Montag, 1. April 2019, 09:30–12:30, H1

The presence of mechanical fields can affect the electrical conductivity by various mechanisms and is typically considered to be detrimental for the materials performance. The idea to intentionally tune functionality by stress or strain is so far typically limited to interface engineering of thin films. The goal of this symposium is to highlight recent developments in the exploration of mechanical coupling of electrical conductivity in electronic, ionic and mixed conducting oxides. Researchers working on nanomaterials, piezoceramics, photovoltaic and mechanically deformed ion conducting materials will present their most recent results. Identification and modeling of common features will create synergies that will foster future progress towards a scale-bridging understanding of this emerging field
